Description
The Omni Instruments Subsea Ultrasonic Flow Meter is a fully bespoke, made-to-order measurement solution engineered for the precision monitoring of clean fluids in extreme deep-sea environments up to 3000 metres. Specifically designed for subsea manifolds and ROV-led operations, this transit-time meter is built to unique client specifications with an optimised bore range of 1″ to 5″ to ensure stable laminar flow and high-integrity sensor performance. Customers can define every critical parameter—from base materials (316 Stainless Steel or Anodised Aluminium) and custom process threads to specialised internal coatings and hydrostatic pressure testing protocols—ensuring a seamless fit into existing subsea infrastructure without the maintenance requirements of mechanical flow meters.
